Herugrim was an ancient sword, an heirloom of the royalty in Rohan.
At the time of King Théoden, the sword was at least five hundred years old. It was at last passed to Théoden, the last king of the second line in Rohan; who won victory with it at Helm's Deep, and died with it in his hand on the Pelennor Fields, outside of Minas Tirith, while aiding Gondor in its plight.
Under the influence of Gríma Wormtongue's leechcraft, Théoden had entrusted the blade to him for safekeeping, but Wormtongue hid it away and allowed it to rust. After Gandalf restored Théoden to himself, Háma the door warden found the sword locked in Gríma's chest.
